Title: Injection die for cassette half
Inventor: TANABE HISANORI
IPC: B29C45/26
Filed: 1989-07-12
Abstract: PURPOSE:To make an external appearance favorable by making gate marks invisible from the outside by positioning the gate makes on the rear of a through hole part, by a method wherein a resin passage communicating with a resin casting port provided on a part of die corresponding to the inside of the through hole. CONSTITUTION:A cylindrical frame 4 is arranged within a movable retainer plate 2 by corresponding to the rear of a through hole part and a tonguelike resin casting port 5 is formed on a part of the cylindrical frame 4. Molten resin is fed into a cavity 3 through a resin passage 9, circular resin passage 6 and the resin casting port 5 of a retainer plate 1. In the case where a product is taken out by breaking a mold after molding, the product is moved along with the movable retainer plate 2 as it is stuck to the movable retainer plate 2. In the case where the product is released by projecting to the movable retainer plate 2 in succession, the resin in the resin casting port 5 part and resin passage 6 is left behind by sticking to the cylindrical frames 4, 7 and a support pin 8. Then a cylindrical frame 7 is projected, the resin in the resin casting port 5 and resin passage is released and removed from the die.

Title: Surface treatment apparatus
Inventor: TSURUTA SHINOBU
IPC: A61L2/10
Filed: 1987-07-21
Abstract: PURPOSE:To increase treatment effect by ultraviolet rays and ozone, by making the interior of a main body to an atmosphere having good ultraviolet ray transmissivity and providing an ozone treatment space to the under surface of a plate body and reducing the distance between a light source and a specimen. CONSTITUTION:For example, reflecting bodies 12 are supported by the inner upper surface of the main body 11 at an interval of about 5cm and an ultraviolet ray generating lamp 13 is mounted in each of the reflecting bodies 12. The main body 11 is evacuated from a nitrogen gas or inert gas supply port 15 also used as a vacuum discharge port or filled with nitrogen gas or inert gas to constitute an atmosphere having good ultraviolet ray transmissivity. Since the illuminance of ultraviolet rays on the surface of a specimen is largely affected by an irradiation distance, the distance between the surface of the specimen and the ultraviolet ray generating lamp 13 is reduced as small as possible in order to increase treatment effect. By this method, the oils and fats. org. solvent, foreign matter, dust and fine powder on the surface of the specimen such as plastic, glass, metal or ceramic can be effectively decomposed and removed by ultraviolet rays and the ozone in the treatment space.

Title: Kerf device for blood pressure measurement
Inventor: MIYAZAWA HIDEKI
IPC: A61B5/022
Filed: 1989-07-13
Abstract: PURPOSE:To carry out the blood pressure measurement with high precision by forming a positioning hole by inserting a pressurized air introducing pipe for a kerf from inside to outside, onto an annular case. CONSTITUTION:An arm at a blood pressure measurement position is inserted into an arm band case 24 from the direction of arrow A, and the artery vein of an arm is set oppositely under a microphone M. Then, the pressurized air is introduced into the inside and outside introducing spaces S1 and S2 through the first and second introducing pipes 22a and 22b, and the korotkoff sound in the artery vein is detected by the microphone M, pressing the arm. Since at this time, the introducing pipes 22a and 22b are installed onto the outside surface of a kerf 21, and the introducing pipes 22a and 22b are positioned at the positioning holes 24a and 24b of the arm band case 24, the shift of the kerf 21 due to the insertion and pulling-out of the arm is prevented. Further, since the bulging-out of the kerf 21 is suppressed at the part P8 which is separated by a prescribed distance from the installation position of the microphone M, the microphone M is positioned always at a proper bulging-out part of the kerf 21, and closely attached onto the artery vein of the arm.

Filed: 1987-07-20
Abstract: PURPOSE:To eliminate the need of a focusing lens, to make the device miniature and light in weight, and to reduce the cost by constituting the end face of a substrate which a light beam emitted and deflected from an optical waveguide passes through, of a lens surface. CONSTITUTION:In accordance with the output of an image signal S, a semiconductor laser 18 is controlled by a driving circuit 20, a voltage whose frequency is varied continuously is applied to an IDT 15 from a driving circuit 17, and an elastic wave 12 is advanced.

Abstract: PURPOSE:To reduce vibration caused at the time when an elevator cage is started to elevate or stopped by providing a pair of guide rollers on the upper and lower portions of the elevator cages in such a manner as to be perpendicular to guide rails, and using the supporting shaft of the guide roller as a sliding bearing. CONSTITUTION:Guide rails 2 are vertically provided along the side wall, and an elevator cage 3 is provided so as to be freely elevated along the rails 2 with a suspending rope 4. A flat supporting plate 20 is laid on the upper portion 3a of the cage 3, and is provided with each bracket 21 in such a manner as to be perpendicular to the guide rails 2. The bracket 21 is rotatably provided with each supporting shaft 22 which is frictionally inserted into each guide roller 23 while being prevented from slipped off with each isolating cylinder 24. The supporting shaft 22 of the guide roller 23 serves as a sliding bearing, the diameter of which is specified to be approximately 0.3 to 0.8 times as large as that of the guide roller 23. Accordingly, in elevating and lowering of the cage 3, there occurs a specified friction between the guide roller 23 and the supporting shaft 22, thereby reducing vibration. Therefore, it is possible to improve the riding comfortable feeling of the cage 3 and the working efficiency of the power.
